Remarks

• Systematics: Orafortis luma appears superficially similar to Eriococcus Targioni Tozzetti Sensu lato species but can be distinguished from all Eriococcus species described from Chile by (1) the distinct aclerotic rim around the dermal orifice of the macrotubular ducts, (2) sclerotic nodules on dorsal surface of posterior abdominal segments, (3) microtubular ducts opening at bases of enlarged dorsal setae, and (4) two size classes of dorsal macrotubular ducts. Only three species of Eriococcus are known from species of Myrtaceae in South America. O. luma can be distinguished from E. jorgenseni by (1) the variable size, and acute apices of the dorsal setae (all dorsal setae are approximately the same size and have rounded apices in E. jorgenseni), (2) 6-segmented antennae (7-segmented in E. jorgenseni) and (3) only 5-10 translucent pores on each hind coxa (ca. 40 large pores in E. jorgenseni). O. luma differs from E. lanatus in the following: (1) test with a distinct anal orifice (no anal orifice detected in E. lanatus, (2) antennae 6-segmented (7-segmented in E. lanatus), (3) only 5-10 translucent pores on each hind coxa (40 or more visible on hind legs of E. lanatus), and all legs not thickened. E. ]erflexus also has 7-segmented antennal and all legs thickened and further differs from O. luma by having only 6 anal ring setae. (Kondo, et al., 2006)
• Structure: Body outline ovate, 1.30-1.64 mm long, 0.90-1.08 mm wide. Eyespot 20 µm wide. All legs with trochanter + femur, tibia + tarsus; all digitules slender with moderately expanded apices; claw denticle present; tranparent pores present as heavidly sclerotized pits with either small circular or irregular slit-like openings. Microtrichia on ventral side of all coxae. (Kondo, et al., 2006)
• Biology: Insect concealed within spiky test, ca. 2 mm long, ca. 1 mm wide, cryptic upon hirsute stems and leaf or stem axils of host. Test comprised of numerous glassy filaments, arising from tightly-woven matrix, with rounded anal opening ca. 0.3 mm in diameter. Test of the male ca. 1.5 mm long, occurring on underside of leaves. (Kondo, et al. 2006)
• General Remarks: Detailed description and illustration in Kondo, et al., 2006.
